Abstract

PURPOSE: To remove suspended solids efficiently from raw water of largely varying turbidities and to obtain clean treated water constantly by adding a contact settling tank to the forestage of a filtration tank.
CONSTITUTION: A flocculant is injected from a flocculant injection pipe 30 into raw water of high turbidity, and both are quickly agitated with an agitator 17 in a mixing tank 16 to form small flocs. The mixed water is flowed from an outlet pipe 15 into the inflow passage 27 of a contact settling tank 18, where it is passed horizontally in packings 22, 23. As the mixed water is passed through the voids in the packings 22, 23 in this way, the mixed water is slowly and quickly agitated by the packings 22, 23, to grow the flocs further and settle the large flocs in the packing 22, 23, thereby lowering the turbidity of the raw water. The water is flowed from an outflow passage 28 through an outlet pipe 2 into the bottom part of a filtration tank 1 at a head. Next, if the turbidity of the raw water is low, the raw water is flowed directly from the mixing tank 16 into the tank 1 through a by-pass pipe 21.
